CVE-2026-19389 1 Redhat 5 Enterprise Linux, Enterprise Linux Eus, Rhel E4s and 2 more 2026-11-04 7.1 High
Multiple integer overflow and underflow vulnerabilities were found in the GStreamer gst-plugins-ugly ASF demuxer (asfdemux) when parsing header objects from crafted ASF, WMV, or WMA files. Insufficient validation of attacker-controlled length and size values can bypass bounds checks and cause out-of-bounds heap reads. This can result in application crash, denial of service, or limited information disclosure when untrusted media is processed.
CVE-2026-18917 1 Redhat 10 Enterprise Linux, Enterprise Linux Eus, Enterprise Linux Nvidia and 7 more 2026-11-04 7.8 High
A flaw was found in libvirt. An unprivileged local user could exploit an integer overflow vulnerability in the NodeGetFreePages RPC handler. This flaw allows crafted values to bypass a size check, leading to an undersized memory buffer. Subsequently, real NUMA node data can overwrite this buffer. This heap buffer overflow can corrupt the root libvirt daemon's memory, potentially leading to a denial of service or local privilege escalation.
CVE-2026-18453 1 Redhat 11 Directory Server, Directory Server E4s, Enterprise Linux and 8 more 2026-11-04 7.5 High
A flaw was found in 389 Directory Server. A missing NULL pointer check in the paged results handling of op_shared_search allows an unauthenticated remote attacker to crash the LDAP server by sending a crafted sequence of search requests using the USE_ONE_BACKEND control, resulting in denial of service.
CVE-2026-18355 1 Redhat 10 Directory Server, Directory Server E4s, Enterprise Linux and 7 more 2026-11-04 7.5 High
A heap buffer overflow flaw was found in the SASL I/O layer of 389 Directory Server (389-ds-base). In sasl_io_start_packet(), the wrapped-record length read from the wire is validated only against an upper bound. A small wire length (0, 1, or 2) produces an encrypted_buffer_count below the already-consumed encrypted_buffer_offset, causing an unsigned subtraction underflow in sasl_io_read_packet(). PR_Recv is then requested to read approximately 4 GiB into a 1024-byte heap buffer, resulting in a heap buffer overflow with attacker-controlled content. After a successful SASL bind with integrity protection (SSF > 0), a remote authenticated attacker can cause a denial of service or potentially achieve remote code execution. This flaw is distinct from CVE-2026-11774, whose fix only guards against upper-bound overflow.
CVE-2026-18147 1 Redhat 9 Enterprise Linux, Enterprise Linux Eus, Freeipa and 6 more 2026-11-04 8.1 High
A flaw was found in FreeIPA. An unauthenticated remote attacker could exploit a DOM Cross-Site Scripting (XSS) vulnerability in the FreeIPA/IdM Web UI password reset page. By enticing a victim to click a specially crafted link and complete a password reset, the attacker could inject and execute arbitrary JavaScript code. This allows the attacker to perform actions within the victim's authenticated session, potentially leading to full administrative control if an IdM administrator is targeted.
CVE-2026-16529 1 Redhat 10 Enterprise Linux, Enterprise Linux Eus, Openshift and 7 more 2026-11-04 7.5 High
A signed integer overflow in the PCP __pmGetPDU() function can be exploited via crafted network packets during PDU processing or SASL negotiation. This permanently blinds the affected daemon, resulting in a total denial of service (DoS) for subsequent packet reads.
CVE-2026-16527 1 Redhat 10 Enterprise Linux, Enterprise Linux Eus, Openshift and 7 more 2026-11-04 7.3 High
An unauthenticated remote attacker can bypass access controls by sending crafted requests to the PCP pmproxy /store endpoint. This allows the attacker to overwrite any PMDA metric, leading to arbitrary code execution and system takeover.
CVE-2026-16526 1 Redhat 10 Enterprise Linux, Enterprise Linux Eus, Openshift and 7 more 2026-11-04 8.8 High
A flaw in the PCP linux_sockets module exposes an unsecured internal connection. An attacker with initial code execution can exploit this to escalate privileges and execute arbitrary commands as root.
CVE-2026-16524 1 Redhat 10 Enterprise Linux, Enterprise Linux Eus, Openshift and 7 more 2026-11-04 7.8 High
A command injection flaw in PCP's linux_sockets PMDA allows malicious shell metacharacters via the network.persocket.filter metric. This failed validation lets attackers execute arbitrary commands as the PMDA user when metrics refresh.
CVE-2026-1933 2 Redhat, Samba 11 Enterprise Linux, Enterprise Linux Eus, Openshift and 8 more 2026-11-04 7.1 High
A flaw was found in Samba’s handling of NTFS-style reparse points on shares configured with read only = yes. Due to missing SMB-layer access checks, authenticated users with underlying filesystem write permissions may create or delete reparse point metadata through SMB operations even on read-only exports. This could allow modification of SMB-visible file behavior, including converting files into symbolic links or other reparse point types.
CVE-2026-1761 1 Redhat 9 Enterprise Linux, Enterprise Linux Eus, Openshift Devspaces and 6 more 2026-11-04 8.6 High
A flaw was found in libsoup. This stack-based buffer overflow vulnerability occurs during the parsing of multipart HTTP responses due to an incorrect length calculation. A remote attacker can exploit this by sending a specially crafted multipart HTTP response, which can lead to memory corruption. This issue may result in application crashes or arbitrary code execution in applications that process untrusted server responses, and it does not require authentication or user interaction.
CVE-2026-120194 3 Json-glib, Red Hat, Redhat 6 Json-glib, Enterprise Linux, Enterprise Linux and 3 more 2026-11-04 7.5 High
A flaw was found in json-glib. The JSONPath slice evaluator used by json_path_query() can enter an infinite loop when given a slice expression with a negative step. An application that evaluates attacker-controlled JSONPath expressions can be forced into a hang, leading to a denial of service.
CVE-2026-119777 2 Red Hat, Redhat 3 Enterprise Linux, Enterprise Linux, Rhel Els 2026-11-04 8.8 High
A flaw was found in GStreamer's gst-plugins-bad H.266/VVC parser. When processing a malformed H.266 media file or stream, an integer overflow while parsing profile, tier, and level fields can lead to a stack-based buffer overflow. An attacker could cause an application to crash and may be able to execute code in the context of the affected application.
CVE-2026-119528 2 Red Hat, Redhat 3 Enterprise Linux, Enterprise Linux, Rhel Els 2026-11-04 7.8 High
A flaw was found in GIMP. The PSD plug-in’s image resource header loader uses an incorrect destination size when copying a converted resource name into a fixed stack buffer. Opening a crafted PSD file can cause a stack-based buffer overflow, leading to a crash and potentially arbitrary code execution.
CVE-2026-13732 1 Redhat 6 Cost Management On Premise, Enterprise Linux, Hardened Images and 3 more 2026-11-04 7 High
A flaw was found in GDB's STABS debug format parser. The read_member_functions() function in gdb/stabsread.c contains a linked list removal bug in the code that separates destructor and non-destructor member functions of C++ classes. The bug causes the destructor entries to remain in the main function list while the list length counter is decremented, resulting in an out-of-bounds write when the function list is copied to its final allocated array. An attacker can craft an ELF binary with malicious .stab and .stabstr sections that triggers this out-of-bounds write when a user opens the file in GDB and performs any symbol-inspection operation such as setting a breakpoint. The inferior process does not need to be executed. Under controlled conditions, this was demonstrated to achieve execution of arbitrary commands within the GDB process.
CVE-2026-13601 2 Gnome, Redhat 8 Yelp, Enterprise Linux, Rhel Aus and 5 more 2026-11-04 7.1 High
A flaw was found in Yelp due to an overly permissive Content Security Policy (CSP) implementation provided by yelp-xsl. A malicious Flatpak application can open crafted help content through the OpenURI portal. By embedding an untrusted CSS stylesheet within a structured SVG document, attacker-controlled content can bypass Flatpak's intended sandbox isolation, allowing Yelp to evaluate local XML inclusions and disclose arbitrary user-readable host files through remote CSS resource requests. This may result in the unauthorized disclosure of sensitive information.
CVE-2026-13097 2 Freeipa, Redhat 9 Freeipa, Enterprise Linux, Enterprise Linux Eus and 6 more 2026-11-04 8.7 High
A privilege escalation flaw was found in FreeIPA. The uniqueness constraint enforced on Kerberos principal name attributes in the 389-ds directory server does not properly account for equivalent representations of the same principal name, allowing a user with sufficient LDAP write privileges to create a service principal that impersonates an existing privileged one. This can lead to unauthorized acquisition of Kerberos service tickets for sensitive services, potentially resulting in full domain compromise.
CVE-2026-12912 2 Libtiff, Redhat 12 Libtiff, Enterprise Linux, Enterprise Linux Eus and 9 more 2026-11-04 7.3 High
A flaw was found in libtiff. A remote attacker could exploit this vulnerability by providing a specially crafted PixarLog-compressed TIFF image. This issue occurs when decoding Pixarlog codec images with the PIXARLOGDATAFMT_8BITABGR output format and a specific stride value, leading to a heap-based buffer overflow. This could potentially result in arbitrary code execution or a denial of service (DoS).
CVE-2026-12505 1 Redhat 5 Cifs-utils, Enterprise Linux, Openshift and 2 more 2026-11-04 7.8 High
A flaw was found in the cifs-utils package where the cifs.upcall helper fails to securely drop its root privileges before looking up user information inside a user-controlled environment. A local, low privileged attacker can exploit this by using a crafted request_key payload to trick the root-owned helper into entering a custom environment (namespace) containing a malicious NSS module. This forces the system to load the attacker's controlled NSS Module and configuration, allowing them to execute arbitrary commands as the root user, elevating their privileges and fully compromising the system.
CVE-2026-12080 2 Qemu, Redhat 5 Qemu, Enterprise Linux, Enterprise Linux Nvidia and 2 more 2026-11-04 7.3 High
A flaw was found in the QEMU Guest Agent (qga). A local unprivileged user can exploit a vulnerability in the guest-ssh-add-authorized-keys command handler by manipulating symbolic links. This can occur either through a deterministic directory-symlink bypass or a Time-of-Check to Time-of-Use (TOCTOU) file-symlink race. Successful exploitation allows the attacker to gain ownership of arbitrary root-owned files or directories, leading to root access. This vulnerability requires an external management layer (e.g., libvirt) to trigger the affected code path.
